can you help me graph this equation x^2+2x+5
\n" ); document.write( "----------
\n" ); document.write( "y = x^2+2x+5
\n" ); document.write( "----
\n" ); document.write( "It is a parabola opening upward.
\n" ); document.write( "It has a minimum at x = -b/2a = -2/2 = -1
\n" ); document.write( "Then f(-1) = 1-2+5 = 4
\n" ); document.write( "So vertex at (-1,4)
\n" ); document.write( "---
\n" ); document.write( "Y-intercept = f(0) = 5
\n" ); document.write( "----
\n" ); document.write( "Plot the vertex and the point (0,5)
\n" ); document.write( "and draw a parabola opening upward though them to get:
